    <p>
    Left and right brackets are used to note vector and matrix concatenation.
    These symbols are also used to denote a multiple left-hand-side for a function 
    call</p>
    <p>
    Inside concatenation brackets, blank or comma characters mean 
    "column concatenation", semicolon and carriage-return mean 
    "row concatenation".</p>
    <p>
    Note : to avoid confusions it is safer to use commas instead of blank to
    separate columns.</p>
    <p>
    Within multiple lhs brackets variable names must be separated by comma.</p>
